Do SMS messages from WhatsApp reach someone who is in your blacklist - in detail?
The functionality of blocking contacts on WhatsApp is designed to prevent unwanted communication, but it is important to understand the limitations and specifics of this feature when it comes to SMS messages.
When you block a contact on WhatsApp, several changes occur in your interaction with that person. Primarily, they are unable to send you messages or view your status updates. Additionally, you will not be able to see their last seen timestamp or online status. However, the blocking feature is specific to the WhatsApp application and does not extend to other communication methods such as SMS.
It is crucial to note that WhatsApp's blacklist only affects communications within the WhatsApp ecosystem. If a blocked contact attempts to send you an SMS message, it will bypass WhatsApp's blocking feature entirely because SMS messages are handled by your mobile carrier's network and not the WhatsApp application itself. This means that any SMS sent from the blocked contact's phone number will be delivered to your device as usual, regardless of their status on your WhatsApp blacklist.
In summary, while blocking a contact on WhatsApp effectively prevents them from sending you messages within the app, it does not affect SMS messaging. Any SMS sent from a blocked contact will reach your phone without any restrictions imposed by WhatsApp's blacklist feature.
